Special Issue Information

Dear Colleagues,

The improvement in computational technology due to the increment in data processing speed, data management, and storage, in addition to the development of mathematical numerical methods, has allowed the possibility to develop complex tools for analyzing problems in all science and engineering fields. In this way, Computational Fluid dynamics (CFDs) has become a powerful tool for reproducing many situations computationally without the need to build a real model. Fluids have a wide range of applications; consequently, the understanding of fluid mechanics is essential to every form of technological development, including engineering, industrial, weather, biology, and medical areas. Thus, the motivation for developing this Special Issue is to expose the importance of fluid flow in all scientific areas. It is a pleasure to invite you to submit research related to experimental CFD, including symmetry, asymmetry, and physical or geometrical descriptions of fluid behavior. The following topics are welcome in this issue:

  1. CFDs with industrial applications, including metallurgical, hydrometallurgical, chemical, fluids inside reactors, and other processing methods.
  2. CFDs with applications in aerodynamics and automotive analysis.
  3. Stationery and dynamic fluid analysis, theoretical and mathematical analysis, and analysis of streams, including the application of numerical models and numerical approaches.
  4. Thermo-fluids, micro-channels, nano-fluids, and mass flow problems.
  5. Hydraulics, hydrodynamics, and magneto-hydrodynamic applications.
  6. Fluids with applications for climate, weather, and environmental examinations.
  7. Fluids flow simulations with biological and medical applications.
  8. The measurement and characterization of fluid properties.
  9. Analysis of laminar, transient, and turbulent fluid flows.
  10. Analysis of fluids in porous media and hydraulics applications.
  11. Analysis of viscosity, inertial, capillarity, and buoyancy forces.
  12. Theoretical and mathematical analysis of fluid mechanic models.
  13. CFD within civil engineering works e.g. bridges, dams, urban drainage systems.
  14. CFD within applications of multiphase flow, turbidity plumes, gravity currents etc.
  15. Advances in Smooth Particle Hydrodynamics

Papers that include the experimental testing and treatment of data obtained with particle indicators, flowmeters, and other instruments are also welcome.

This study investigates the asymmetric effects applying heat transfer as a diagnostic tool in dendritic networks with symmetrical branching, characterized by the geometric property of self-similarity. Using a Computational Fluid Dynamics (CFD) model, we analyze five structural isomers of a three-level dichotomous branching network to evaluate the relationship between fluid dynamics, heat transfer, and geometric configuration. The main constraints are geometrical; that is, the volume at each branching level remains constant, and homothetic relationships respect the Hess–Murray law both for diameters and angles between sister tubes. The model considers an incompressible and stationary Newtonian fluid flow with Reynolds numbers ranging from 10 to 2000 and heat transfer in the range 1 to 1000 W/m2. Our results show that significant asymmetries in flow distribution and temperature profiles emerge in these symmetric structures, primarily due to the successive alignment of tubes between different branching levels. We found that the isomer with the lowest pressure drop is not the same as the one providing the most uniform flow distribution. Crucially, thermal analysis proves to be more sensitive than fluid dynamic analysis for detecting flow asymmetries, particularly at low Reynolds numbers less than 50 and q″ = 1000 W/m2. While heat transfer does not significantly alter the fluid dynamic asymmetry, its application as a diagnostic tool for identifying flow asymmetries is effective and crucial for such purposes.
